This is a global plan to revamp the theme infrastructure in Tiki. This is led by the UX Team. Please join us!

As of Tiki11, the Tiki theme infrastructure is increasingly due for a revamp to take advantage of advances in technology

Thus, in Tiki 13, we are going all out on "Mobile-first" Bootstrap 3.0

When

Any non-disruptive work should be done as soon as possible. Ex.: Fonts.
For disruptive work (ex.: CSS consolidation), Tiki13 after the Tiki12LTS would be a great time to revamp the whole theme management in Tiki.

The bulk of the work could be done at one or two TikiFest Design Revamp

For whom

There are 3 target audiences

For them, themes is just one of a thousand features and they just pick it. (Can be documented at doc.tiki.org)

They like things like Skeleton.css or http://dev.tiki.org/CSS+Frameworks+and+Preprocessors#Twitter_Bootstrap
How to avoid to get in their way

All the action should be on themes.tiki.org

Why Tiki themes never look WOW
CSS Frameworks and Preprocessors
- Using Less CSS with Tiki
Deployment of themes: Mods or profiles? If we continue with mods, we should improve them
theme & css work, including Simplification of CSS
+ One target: reduce module content specific rules with module zone specific rules (needed because a module can be placed anywhere, and different zones have different colors, etc.)
- Rethink function and location of various CSS files (css directory vs. styles directory, feature-specific (admin.css) vs. global (layout.css and theme stylesheets), etc.
  Reduce redundant rules (no need to specify body in three or four files, etc.)
